I'd be a little leery of 3 ton for a 24'. Go for 6 ton and you'll be okay.
Agreed. As a general rule, I use hydraulic jacks that are capable of lifting the entire vehicle. So, I'd only use a 3-ton jack on vehicles with a GVW of less than 6,000 pounds.
Also, use a 2 foot by 2 foot piece of 3/4" plywood under the jack. There's less chance of the jack digging into the dirt or tar and tipping over. (2'x 2'x 3/4" is the minimum ... a piece of 1-1/8" subfloor or two pieces of 3/4" would be better.)
Finally, use jack stands, rated at a minimum of 6-tons each, even if you're just changing a tire. (Also with plywood under them.)
This is based on over 40 years experience with "jack disasters." As a result of past experience, I don't like raising a vehicle any higher than I have to and do everything I can to make sure it doesn't come back down until I'm ready for it to do so. (I also place one or two spare tires under the axle to catch it if something goes wrong.)
P.S. Concrete blocks are NOT, repeat NOT, good for supporting vehicles. (A tap of a hammer is all it takes to shatter them when they're under load.)
